dibac4 (3) [5], dibac4 (3) the negative charge of anionic slow response is the most commonly used fluorescent membrane potential probe. Probe itself is not fluorescent, fluorescence, the measurement needs to be immersed in the fluorescent dye when the enter the cytoplasm of cells and proteins within cells. When cell fluorescence intensity increased, indicating that the increase in the membrane potential depolarization; On the other hand, the fluorescence intensity of the membrane potential to reduce cell hyperpolarization. Rhodamine 123 is mainly used for the determination of mitochondrial membrane potential [6].
This suggests that changes in cellular structure and mechanisms used to study the composition of the cytoskeleton, cell membrane structure and macromolecular assembly. As a messenger at the same time, the ring gland cracking of single nucleotide overcast camp is also concern: Nagai, the use of the resonance observed cyclic adenosine diphosphate-induced phosphorylation of living cells are dynamic changes in protein kinase in cameleons-2 curve transformation Pierce and other using cameleons labeled metallothionein (machine translation), studies nitric oxide stimulation machine translation function. Cell communication research: laser scanning confocal microscope to measure the molecular cell gap junction-mediated transfer observed adjacent cells, cell communication. Used to study tumor promoters, growth factors and intracellular calcium, PH value and intercellular communication gap between the camp and the cell.
As the dichroic mirror splitting effect of residual laser light reflecting dichroic mirror will not be discovered. Figure 2 illustrates the role played by the shooting holes: only the point of the focal plane of light through the outlet hole; outside the focal plane of the outlet aperture of the light emitted, in the focus of the aircraft, most can not through the center hole. Therefore, the focal plane of the observation point on the target display light, instead of the observation point is used as a black background, contrast enhancement, image clarity. In the imaging process, the export position of the hole is always focusing microscope objective lens (focus) is one-to-one relationship (conjugate), which is called the confocal microscope (consultation and coordination).
